Product parameters

High Power Graphite Electrode

HP Graphite Electrode

1.The high power graphite electrode uses calcine petroleum coke,Japanese imports of needle coke and temperature modified asphalt as raw material,in accordance with the high power graphite electrode production processes,crushing,screening,dosing,kneading,forming,baking,hi pressure impregnation,the second time of baking,graphitization and machining refined.

2.The nipple uses Japanese imports of needle coke,three times of baking processes.
